Het weer in Copán (Copán Ruinas) in mei

Semuc Champey-forum threads on the wetter months describe real heavy rain as capable of turning the famous turquoise pools brown, posters calling this outcome uncommon but genuinely possible after a serious system moves through. Regulars call the drier season broadly November or December through April the more reliable stretch for clearer water, May sitting right at the edge of that window. Posters describe the approach road from Lanquin as rough regardless of season, real 4x4 capability recommended given how poor conditions get after rain. Regulars call swimming in the pools the clear highlight whenever water clarity cooperates, checking recent conditions with a local guide worth doing. Posters recommend real waterproof gear and flexible plans given how quickly conditions shift. Regulars call the setting worth visiting regardless of exact water color. The record: 31.7C days feeling like a punishing 38C, 22.9C nights, 146.9mm across 18 days and 79 percent humidity.

Copán Ruinas forum posters are consistent that July, though squarely in the rainy season, doesn't mean a lost day: mornings are usually clear and pleasant for touring the ruins, with the rain typically arriving as a dramatic hour-or-two downpour in the late afternoon or evening. One traveler specifically said full-day rain or drizzle was rare during their visit. The advice that comes up again and again is to plan ruins-and-outdoor time for the morning and treat the afternoon storm as a good excuse for a long lunch, since it genuinely shouldn't derail a trip.

Forum posters describe November through March as a genuinely nice stretch here, with January - the coolest month of the year - still comfortably mild rather than cold, thanks to the town's highland setting keeping temperatures well short of the lowland heat found elsewhere in Honduras. Posters consistently recommend staying in Copan Ruinas town itself rather than the outskirts, calling it a pleasant, walkable base for exploring the nearby Maya ruins. One forum thread specifically discusses planning a January/February trip to Honduras as a winter escape, with posters framing this window as a reliable, comfortable choice for ruins-focused sightseeing.
